Zero-shot audio captioning with audio-language model guidance and audio context keywords

Description

This repository is the official implementation of the NeurIPS 2023 - Machine Learning for Audio Workshop (Oral) Zero-shot audio captioning with audio-language model guidance and audio context keywords by Leonard Salewski, Stefan Fauth, A. Sophia Koepke, and Zeynep Akata from the University of Tübingen and the Tübingen AI Center. You can find an ArXiv pre-print here.

Abstract

Zero-shot audio captioning aims at automatically generating descriptive textual captions for audio content without prior training for this task. Different from speech recognition which translates audio content that contains spoken language into text, audio captioning is commonly concerned with ambient sounds, or sounds produced by a human performing an action. Inspired by zero-shot image captioning methods, we propose ZerAuCap, a novel framework for summarising such general audio signals in a text caption without requiring task-specific training. In particular, our framework exploits a pre-trained large language model (LLM) for generating the text which is guided by a pre-trained audio-language model to produce captions that describe the audio content. Additionally, we use audio context keywords that prompt the language model to generate text that is broadly relevant to sounds. Our proposed framework achieves state-of-the-art results in zero-shot audio captioning on the AudioCaps and Clotho datasets.
